Description

Die Erfindung betrifft eine Geschirrspülmaschine mit einem Spülbehälter.The invention relates to a dishwasher with a washing container.

Eine Geschirrspülmaschine weist bekanntlich ein Spülverfahren auf, dessen Programmablauf aus wenigstens einem Teilprogrammschritt "Vorspülen", einem Teilprogrammschritt "Reinigen", wenigstens einem Teilprogrammschritt "Zwischenspülen", einem Teilprogrammschritt "Klarspülen" und einem Teilprogrammschritt "Trocknen" besteht. Zur Erhöhung des Reinigungseffekts wird dabei die Spülflüssigkeit vor oder während eines Teilprogrammschrittes erwärmt. Die Erwärmung der Spülflüssigkeit erfolgt üblicherweise mittels elektrischer Heizungen. Zur Trocknung von Spülgut in einer Geschirrspülmaschine sind unterschiedliche Trocknungssysteme bekannt.A dishwasher has, as is known, a rinsing process whose program sequence consists of at least one partial program step "pre-rinsing", one sub-program step "cleaning", at least one sub-program step "intermediate rinsing", one sub-program step "rinsing" and one sub-program step "drying". To increase the cleaning effect while the rinsing liquid is heated before or during a Teilprogrammschrittes. The heating of the rinsing liquid is usually carried out by means of electric heaters. For drying items to be washed in a dishwasher different drying systems are known.

Beispielsweise kann das Spülgut durch Eigenwärmetrocknung getrocknet werden, wenn die Spülflüssigkeit in einem Teilprogrammschritt "Klarspülen" erhitzt wird und somit das heiß klargespülte Spülgut durch die so aufgebaute Eigenwärme des Spülguts während des Trocknungsvorgangs von selbst trocknet. Um diese Eigenwärmetrocknung zu erreichen, wird die Spülflüssigkeit in dem Teilprogrammschritt "Klarspülen" auf eine bestimmte Temperatur erwärmt und über Sprüheinrichtungen auf das Spülgut aufgebracht. Durch die relativ hohe Temperatur der Spülflüssigkeit in dem Teilprogrammschritt "Klarspülen" von üblicherweise von 65°C bis 75°C wird erreicht, dass eine hinreichend große Wärmemenge auf das Spülgut übertragen wird, so dass das am Spülgut anhaftende Wasser durch die im Spülgut gespeicherte Wärme verdampft.For example, the items to be washed can be dried by self-heat drying if the rinsing liquid is heated in a rinse-out subprogram step and the hot, rinsed items are automatically dried by the self-heat of the item to be washed during the drying process. In order to achieve this self-heat drying, the rinsing liquid is heated to a certain temperature in the partial program step "rinsing" and applied to the items to be washed by means of spraying. Due to the relatively high temperature of the rinsing liquid in the partial program step "rinsing" usually from 65 ° C to 75 ° C is achieved that a sufficiently large amount of heat is transferred to the items to be washed, so that the water adhering to the items by the heat stored in the items to be washed evaporated.

Bei einer weiteren bekannten Trocknungseinrichtung wird eine separate Heizquelle, z.B. ein Heißluftgebläse, im Spülbehälter dazu verwendet, das feuchte Luftgemisch beim Trocknungsvorgang zu erwärmen, damit die Luft im Spülbehälter eine größere Menge an Feuchtigkeit aufnehmen kann.In another known drying device, a separate heating source, e.g. a hot air blower, used in the rinsing tank to heat the humid air mixture during the drying process, so that the air in the washing container can absorb a larger amount of moisture.

Es sind Geschirrspülmaschinen bekannt, bei denen die Feuchtluft nach außen abgelassen wird. Dies ist nachteilig, da die umgebenden Küchenmöbel geschädigt werden. Daher sind weitere Geschirrspülmaschinen bekannt, bei denen die Feuchtluft vor dem Ausleiten über Kondensationsflächen geleitet wird, an denen die Feuchtigkeit kondensiert. Dieses Kondenswasser wird entweder in den Spülbehälter oder in spezielle Auffangbehälter geleitet.There are known dishwashers in which the moist air is discharged to the outside. This is disadvantageous because the surrounding kitchen furniture is damaged. Therefore, other dishwashers are known in which the moist air is passed before passing over condensation surfaces, where the moisture condenses. This condensation water is directed either into the rinsing container or into special collection containers.

Aus der DE 30 21 746 A1 ist ein Verfahren zum Betreiben einer Geschirrspülmaschine bekannt, bei dem ein wärmeleitend mit dem Spülbehälter verbundener Wärmetauscher während eines Teilprogrammschrittes "Trocknen" mit kaltem Frischwasser gespeist wird. Dadurch wird eine Kondensationsfläche auf der Innenseite des Spülbehälters erzeugt, an der die Feuchtigkeit kondensiert und das entstehende Kondenswasser im Spülbehälter verbleibt. Da der Temperaturunterschied zwischen der Feuchtluft und dem eingefüllten Frischwasser relativ gering ist und die Frischwassermenge sich stetig erwärmt, ergibt sich der Nachteil, dass die Kondensation der Feuchtluft lange dauert und stetig geringer wird, so dass der Auslass an Feuchtluft aus der Geschirrspülmaschine ansteigt und die Dauer des Teilprogrammschrittes "Trocknen" lang ist, bei mäßigem Trocknungsergebnis.From the DE 30 21 746 A1 a method for operating a dishwasher is known in which a heat-conducting connected to the washing tank heat exchanger is fed during a part program step "drying" with cold fresh water. As a result, a condensation surface is produced on the inside of the washing container, at which the moisture condenses and the resulting condensation remains in the washing container. Since the temperature difference between the moist air and the filled fresh water is relatively low and the amount of fresh water is constantly heated, there is the disadvantage that the condensation of the moist air takes a long time and is steadily lower, so that the outlet of moist air from the dishwasher increases and the duration of the partial program step "drying" is long, with moderate drying result.

Ein Nachteil bei den oben beschriebenen Heizungssysteme nach dem weiter oben beschriebenen Stand der Technik besteht darin, dass die Erwärmung der Spülflüssigkeit mit einem hohen Energiebedarf verbunden ist und die benötigte Wärmeenergie für jede Erwärmungsphase mittels der elektrischen Heizelemente neu erzeugt werden muss. Ebenso haben die bekannten Heizungssysteme den Nachteil, dass die Erwärmung der Spülflüssigkeit im Teilprogrammschritt "Klarspülen" sowie die Vorgänge im Teilprogrammschritt "Trocknen" selbst mit einem hohen Energiebedarf verbunden sind und die benötigte Wärmeenergie nach dem Trocknungsvorgang verloren geht.A disadvantage of the heating systems described above according to the prior art described above is that the heating of the rinsing liquid is associated with a high energy requirement and the required heat energy must be regenerated for each heating phase by means of the electrical heating elements. Likewise, the known heating systems have the disadvantage that the heating of the rinsing liquid in the partial program step "rinse" and the operations in the sub-program step "drying" are themselves associated with a high energy demand and the required heat energy is lost after the drying process.

Aus der DE 198 13924 A1 ist eine Geschirrspülwaschine mit einem Spülbehälter bekannt, in der ein Peltier element zuw Enteiehen von wärmeenergie vorgesehen ist.From the DE 198 13924 A1 is a dishwasher with a rinsing known, in which a Peltier element zuw Enteiehen of heat energy is provided.

Aufgabe der vorliegenden Erfindung ist es daher, eine Geschirrspülmaschine bereitzustellen, mit der es möglich ist, unter wirtschaftlichen Gesichtspunkten das im Spülbehälter befindliche Spülgut effizient zu reinigen und zu trocknen sowie den damit verbundenen Energieaufwand so gering wie möglich zu halten.It is therefore an object of the present invention to provide a dishwasher with which it is possible to efficiently clean and dry the items to be washed located in the washing container, and to keep the associated energy expenditure as low as possible from an economic point of view.

Diese Aufgabe wird durch die erfindungsgemäße Geschirrspülmaschine mit den Merkmalen gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der vorliegenden Erfindung sind in den Unteransprüchen gekennzeichnet.This object is achieved by the dishwasher according to the invention having the features according to claim 1. Advantageous developments of the present invention are characterized in the subclaims.

Die erfindungsgemäße Geschirrspülmaschine mit einem Spülbehälter weist mit dem Spülbehälter luftleitend verbundenes Leitungssystem auf, in dem wenigstens ein Peltierelement angeordnet ist, wobei das Peltierelement einerseits zur Abkühlung und dadurch zur Trocknung als auch andererseits zur Erwärmung durchgeleiteter Luft aus dem Spülbehälter verwendet wird.The dishwashing machine according to the invention with a rinsing container has a line system connected in an air-conducting manner to the rinsing container in which at least one Peltier element is arranged, the Peltier element being used on the one hand for cooling and thereby drying and on the other hand for heating air conducted through from the rinsing container.

Durch den Einsatz eines Peltierelements ist nur noch eine gegenüber dem Stand der Technik wesentlich geringere Erwärmung des zu behandelnden Gutes notwendig, z.B. bei Geschirrspülmaschinen im Teilprogrammschritt "Klarspülen". Dies bedeutet eine wesentliche Energieeinsparung. Durch das Abkühlen der Luft wird deren Feuchtigkeitsaufnahmekapazität abgesenkt und der Feuchtigkeitsanteil der Luft fällt als Kondensat aus. Durch die Erwärmung der Luft wird deren Feuchtigkeitsaufnahmekapazität bei jedem Durchleiten durch das Leitungssystem wieder erhöht, was zur Verbesserung des Trocknungsergebnisses und/oder zur Verkürzung der Trocknungszeit führt. Bei dem geschlossenen Luftsystem ist ein Austausch von verschmutzter Luft aus der Umgebung vollständig ausgeschlossen, womit eine Rückanschmutzung des behandelten Gutes verhindert wird. Mit der vorliegenden Erfindung ist eine Geschirrspülmaschine bereitgestellt, mit der es möglich ist, unter wirtschaftlichen Gesichtspunkten das im Spülbehälter befindliche Spülgut effizient zu reinigen und zu trocknen sowie den damit verbundenen Energieaufwand so gering wie möglich zu halten.The use of a Peltier element only requires a considerably lower heating of the material to be treated compared to the prior art, e.g. for dishwashers in the partial program step "rinsing". This means a significant energy saving. By cooling the air, its moisture absorption capacity is lowered and the moisture content of the air precipitates as condensate. By heating the air whose moisture absorption capacity is increased again with each passing through the piping system, resulting in the improvement of the drying result and / or to shorten the drying time. In the closed air system, a replacement of polluted air from the environment is completely excluded, thus preventing back soiling of the treated material. With the present invention, a dishwasher is provided, with which it is possible to efficiently clean and dry the dishes located in the washing container and to keep the associated energy consumption as low as possible.

Nach einem bevorzugten Merkmal der Erfindung wird Luft aus dem Spülbehälter in dem wenigstens einen Teilprogrammschritt "Trocknen" in das Leitungssystem und wieder zurück in den Spülbehälter geleitet, womit die oben erwähnten Vorteile in der erfindungsgemäßen Geschirrspülmaschine bestimmungsgemäß eingesetzt werden.According to a preferred feature of the invention, air is passed from the washing container in the at least one partial program step "drying" in the line system and back into the washing, whereby the above-mentioned advantages in the dishwasher according to the invention are used as intended.

In besonders vorteilhafter Weise weist der Spülbehälter einen Auslass mit einer Leitung zum einen Teil des Peltierelements, eine Leitung vom einen Teil des Peltierelements zum anderen Teil des Peltierelements und einen Einlass mit einer Leitung von dem anderen Teil des Peltierelements auf, wobei in der Leitung zum einen Teil des Peltierelements ein Gebläse angeordnet ist, das wenigstens einen Teil der Luft im Spülbehälter dem Leitungssystem wenigstens zeitweise zuführt. Bei dem geschlossenen Luftsystem ist ein Austausch von verschmutzter Luft aus der Umgebung vollständig ausgeschlossen, womit eine Rückanschmutzung des behandelten Gutes verhindert wird. Das Gebläse lässt sich leicht ansteuern, so dass der Einsatz des Peltierelements genau und einfacher gesteuert werden kann. Außerdem verstärkt das Gebläse die Wirkung des Peltierelements, da die durchzuleitende Luft schneller gefördert wird.In a particularly advantageous manner, the washing container has an outlet with a line to a part of the Peltier element, a line from one part of the Peltier element to the other part of the Peltier element and an inlet with a line from the other part of the Peltier element, wherein in the line to one Part of the Peltier element, a fan is arranged, which supplies at least a portion of the air in the washing container to the line system at least temporarily. In the closed air system, a replacement of polluted air from the environment is completely excluded, which a Rückanschmutzung the treated material is prevented. The blower is easy to control, so that the use of the Peltier element can be precisely and easily controlled. In addition, the fan increases the effect of the Peltier element, since the air to be conveyed is conveyed faster.

Nach einem weiteren bevorzugten Merkmal der Erfindung wird die Luft mittels des Peltierelements abgekühlt. Damit wird die eigentliche Funktion eines Peltierelements, die Abkühlung unter Abtransport der aufgenommenen Wärmeenergie eingesetzt. Durch das Abkühlen der Luft wird deren Feuchtigkeitsaufnahmekapazität abgesenkt und der Feuchtigkeitsanteil der Luft fällt als Kondensat aus.According to another preferred feature of the invention, the air is cooled by means of the Peltier element. Thus, the actual function of a Peltier element, the cooling is used with removal of the absorbed heat energy. By cooling the air, its moisture absorption capacity is lowered and the moisture content of the air precipitates as condensate.

Nach einem weiteren bevorzugten Merkmal der Erfindung wird die Luft mittels des Peltierelements erwärmt. Damit wird die weitere Funktion des ohnehin vorhandenen Peltierelements - die transportierte Wärme aufgenommen beim Kühlen der Feuchtluft und beim Kondensieren der Feuchtigkeit aus der Feuchtluft - zur weiteren Energieeinsparung verwendet.According to another preferred feature of the invention, the air is heated by means of the Peltier element. Thus, the further function of the already existing Peltier element - the heat absorbed when cooling the moist air and condensing the moisture from the moist air - used for further energy conservation.

Nach einer vorteilhaften Ausführungsform der Erfindung ist in der Leitung zwischen dem anderen Teil des Peltierelements und dem Einlass eine Heizung angeordnet. Sollte die Erwärmung der Luft durch das Peltierelement nicht ausreichen, wird zur Sicherstellung der Trocknungsfunktion die Luft zusätzlich mit einer Heizung erwärmt. Trotz des zusätzlichen Energieverbrauchs für die Heizung wird gegenüber dem vorbeschriebenen Stand der Technik eine Energieeinsparung erreicht.According to an advantageous embodiment of the invention, a heater is arranged in the line between the other part of the Peltier element and the inlet. If the heating of the air by the Peltier element is not sufficient, the air is additionally heated with a heater to ensure the drying function. Despite the additional energy consumption for the heating energy savings compared to the above-described prior art is achieved.

Nach einer weiteren vorteilhaften Ausführungsform der Erfindung ist in der Leitung zwischen dem Auslass und dem einen Teil des Peltierelements oder alternativ in der Leitung zwischen dem einen Teil des Peltierelements und dem anderen Teil des Peltierelements ein Kondensor angeordnet. Sollte der Feuchtigkeitsentzug der Luft durch das Wärmerohr nicht ausreichen, wird zur Sicherstellung der Trocknungsfunktion die Luft zusätzlich an einem Kondensor vorbeigeleitet, der den fehlenden Feuchtigkeitsentzug vornimmt.According to a further advantageous embodiment of the invention, a condenser is arranged in the line between the outlet and the one part of the Peltier element or alternatively in the line between the one part of the Peltier element and the other part of the Peltier element. If the dehumidification of the air through the heat pipe is not sufficient, the air is additionally passed to a condenser to ensure the drying function, which performs the missing dehumidification.

Die Erfindung wird nachstehend anhand dem in der Zeichnung dargestellten Ausführungsbeispiel einer erfindungsgemäßen Geschirrspülmaschine erläutert.The invention will be explained below with reference to the embodiment of a dishwasher according to the invention shown in the drawing.

Die einzige Figur zeigt eine erfindungsgemäße Geschirrspülmaschine 1 in schematischer Darstellungsweise mit einem Spülbehälter 2 in dem nicht dargestellte Geschirrkörbe zur Einordnung von nicht dargestelltem Spülgut angeordnet sind.The single FIGURE shows a dishwasher 1 according to the invention in a schematic representation with a washing container 2 in which dish baskets, not shown, are arranged for the arrangement of items not shown.

Erfindungsgemäß weist die Geschirrspülmaschine 1 ein mit dem Spülbehälter 2 luftleitend verbundenes Leitungssystem 4 auf, in dem wenigstens ein Peltierelement 10 angeordnet ist, wobei das Peltierelement 10, wie weiter unten näher erläutert wird, einerseits zur Abkühlung und dadurch zur Trocknung als auch andererseits zur Erwärmung durchgeleiteter Luft aus dem Spülbehälter 2 verwendet wird.According to the invention, the dishwasher 1 has an air line connected to the washing container 2 piping system 4, in which at least one Peltier element 10 is arranged, the Peltier element 10, as will be explained below, on the one hand for cooling and thereby for drying and on the other hand for heating durchgeleiteter Air from the washing compartment 2 is used.

Wie an sich bekannt, ist ein Peltierelement 10 eine Wärmepumpe mit der einem Bereich Wärme entzogen - dieser abgekühlt wird - und zu einem anderen Bereich transportiert wird - dieser erwärmt wird, wobei die Wärme in großer Geschwindigkeit und großer Menge von einem Teil 11 - der sogenannten "kalten Seite" - des Peltierelements 10 zu dem anderen Teil 12 - der sogenannten "warmen Seite" - des Peltierelements 10 geleitet wird. Hierzu liegt an dem Peltierelement elektrischer Strom an. Wird also die eingeleitete Feuchtluft zur "kalten Seite" 11 des Peltierelements 10 geleitet, kühlt dieser die Feuchtluft und verringert damit das Feuchtigkeitsaufnahmevermögen der Feuchtluft, wodurch die in der Feuchtluft enthaltene Feuchtigkeit kondensiert. Die "kalte Seite" 11 des Peltierelements 10 entzieht der Feuchtluft damit die Wärme (sensible Wärme) und nimmt auch die entstehende Kondensationswärme (latente Wärme) auf und transportiert die Wärme zum anderen Teil 12 - zur "warmen Seite" des Peltierelements 10.As known per se, a Peltier element 10 is a heat pump with a heat extracted area - this is cooled - and transported to another area - this is heated, the heat at high speed and large amount of a part 11 - the so-called "cold side" - the Peltier element 10 to the other part 12 - the so-called "warm side" - the Peltier element 10 is passed. For this purpose, electrical current is applied to the Peltier element. Thus, if the introduced moist air to the "cold side" 11 of the Peltier element 10, this cools the moist air and thus reduces the moisture absorption capacity of the moist air, whereby the moisture contained in the moist air condenses. The "cold side" 11 of the Peltier element 10 thus removes the heat from the moist air (sensible heat) and also absorbs the heat of condensation (latent heat) and transports the heat to the other part 12 - to the "warm side" of the Peltier element 10.

Der Spülbehälter 2 weist einen Auslass 3 auf, der zu dem Leitungssystem 4 mit einer Leitung 5 zum einen Teil 11 des Peltierelements 10, mit einer Leitung 6 vom einen Teil 11 des Peltierelements 10 zum anderen Teil 12 des Peltierelements 10 und mit einer Leitung 7 von dem anderen Teil 12 des Peltierelements 10 zu einem Einlass 8 des Spülbehälter 2 führt, wobei in der Leitung 5 zum einen Teil 11 des Peltierelements 10 ein Gebläse 9 angeordnet ist, das wenigstens einen Teil der Luft im Spülbehälter 2 dem Leitungssystem 4 wenigstens zeitweise zuführt.The rinsing container 2 has an outlet 3 which leads to the line system 4 with a line 5 for a part 11 of the Peltier element 10, with a line 6 from one part 11 of the Peltier element 10 to the other part 12 of the Peltier element 10 and with a line 7 of FIG the other part 12 of the Peltier element 10 leads to an inlet 8 of the washing container 2, wherein in the conduit 5 to a part 11 of the Peltier element 10, a fan 9 is arranged, which supplies at least a portion of the air in the washing tank 2 the conduit system 4 at least temporarily.

Bei dem geschlossenen Luftleitungssystem 4 ist ein Austausch von verschmutzter Luft aus der Umgebung vollständig ausgeschlossen, womit eine Rückanschmutzung des behandelten Gutes verhindert wird.In the closed air duct system 4, an exchange of polluted air from the environment is completely excluded, whereby a Rückanschmutzung the treated material is prevented.

In der Leitung 7 von dem anderen Teil 12 des Peltierelements 10 zu dem Einlass 8 des Spülbehälter 2 ist eine Heizung 15 angeordnet. Sollte die Erwärmung der Luft durch das Peltierelement 10 nicht ausreichen, wird zur Sicherstellung der Trocknungsfunktion die Luft zusätzlich mit der Heizung 15 erwärmt. Trotz des zusätzlichen Energieverbrauchs für die Heizung 15 wird gegenüber dem vorbeschriebenen Stand der Technik eine Energieeinsparung erreicht.In the conduit 7 from the other part 12 of the Peltier element 10 to the inlet 8 of the washing compartment 2, a heater 15 is arranged. If the heating of the air by the Peltier element 10 is insufficient, the air is additionally heated by the heater 15 to ensure the drying function. Despite the additional energy consumption for the heater 15, energy savings are achieved over the prior art described above.

In der Leitung 6 vom einen Teil 11 - der "kalten Seite" -des Peltierelements 10 zum anderen Teil 12 - zur "warmen Seite" - des Peltierelements 10 ist ein Kondensor 16 angeordnet. Alternativ ist auch eine Anordnung des Kondensors in der Leitung zum einen Teil - zur "kalten Seite" - des Peltierelements möglich. Sollte der Feuchtigkeitsentzug der Luft durch das Peltierelement 10 nicht ausreichen, wird zur Sicherstellung der Trocknungsfunktion die Luft zusätzlich an dem Kondensor 16 vorbeigeleitet, der den fehlenden Feuchtigkeitsentzug vornimmt. Dieser Kondensor 16 steht in thermischem Kontakt mit der Umgebung.In the line 6 from a part 11 - the "cold side" of the Peltier element 10 to the other part 12 - to the "warm side" - of the Peltier element 10, a condenser 16 is arranged. Alternatively, an arrangement of the condenser in the line to a part - to the "cold side" - of the Peltier element possible. If the dehumidification of the air by the Peltier element 10 is insufficient, the air is additionally conducted past the condenser 16 to ensure the drying function, which carries out the lack of dehumidification. This condenser 16 is in thermal contact with the environment.

Im folgenden wird das bei Betrieb der erfindungsgemäßen Geschirrspülmaschine 1 durchgeführte Verfahren beschrieben.In the following, the method performed during operation of the dishwasher 1 according to the invention will be described.

Eine Geschirrspülmaschine 1 weist bekanntlich ein Spülverfahren auf, dessen Programmablauf z.B. aus wenigstens einem Teilprogrammschritt "Vorspülen", einem Teilprogrammschritt "Reinigen", wenigstens einem Teilprogrammschritt "Zwischenspülen", einem Teilprogrammschritt "Klarspülen" und einem Teilprogrammschritt "Trocknen" besteht. Erfindungsgemäß wird Luft aus dem Spülbehälter 2 während des Teilprogrammschritts "Trocknen" durch das Leitungssystem 4 und wieder zurück in den Spülbehälter 2 geleitet. Hierzu wird das Gebläse 9 eingeschaltet. Der Luftweg ist mit den Pfeilen A, B, C und D angedeutet. Der von dem Gebläse 9 über die Leitung 5 zum einen Teil 11 - zur "kalten Seite"- des Peltierelements 10 geleitete Luft wird an der "kalten Seite" 11 des Peltierelements 10 sehr viel Wärmeenergie entzogen, so dass sie sehr stark abkühlt und da kalte Luft ein wesentlich geringeres Feuchtigkeitsaufnahmevermögen hat, wird dabei ein großer Anteil der Feuchtigkeit kondensiert. Zur guten Wärmeleitung von der Luft zum Peltierelement 10 sind Wärmeleitrippen 13 angeordnet. Das Peltierelement 10 leitet die der Feuchtluft entzogene Wärme (sensible Wärme) und die bei der Kondensierung entstehende Wärme (latente Wärme) zu seinem anderen Teil 12 - der "warmen Seite" des Peltierelements 10. Hierzu liegt an dem Peltierelement 10 elektrischer Strom an. Die nun sehr trockene Luft gelangt über die Leitung 6 vom einen Teil 11 des Peltierelements 10 zum anderen Teil 12 des Peltierelements 10 und wird dort erwärmt. Zur guten Wärmeleitung vom Peltierelement 10 zu der Luft sind Wärmeleitrippen 14 angeordnet. Die nun erwärmte und sehr trockene Luft gelangt nun über die Leitung 7 von dem anderen Teil 12 des Peltierelements 10 zu dem Einlass 8 des Spülbehälter 2 und damit wieder in den Spülbehälter 2. Die in den Spülbehälter 2 eingeleitete, erwärmte Luft ist nun wesentlich trockener und weißt ein hohes Aufnahmevermögen für Feuchtigkeit auf. Sie steigt im Spülbehälter 2 nach oben und nimmt die Restfeuchtigkeit an dem Spülgut auf. Sie wird nun, wie oben schon beschrieben, wieder dem Peltierelement 10 zugeleitet.A dishwasher 1 has, as is known, a rinsing method whose program sequence consists, for example, of at least one partial program step "pre-rinsing", one sub-program step "cleaning", at least one sub-program step "intermediate rinsing", one sub-program step "rinsing" and one partial program step "drying". According to the invention, air is led out of the rinsing container 2 during the partial program step "drying" through the line system 4 and back into the rinsing container 2. For this purpose, the blower 9 is turned on. The airway is indicated by the arrows A, B, C and D. The air guided by the blower 9 via the line 5 to a part 11 - to the "cold side" - of the Peltier element 10 is removed from the "cold side" 11 of the Peltier element 10 very much heat energy, so that it cools very strong and there cold Air has a much lower moisture absorption capacity, it is a large proportion of the moisture condenses. For good heat conduction from the air to the Peltier element 10, heat-conducting ribs 13 are arranged. The Peltier element 10 conducts the heat removed from the moist air (sensible heat) and the heat produced during the condensation (latent heat) to its other part 12 - the "warm side" of the Peltier element 10. For this purpose, electrical current is applied to the Peltier element 10. The now very dry air passes via the line 6 from one part 11 of the Peltier element 10 to the other part 12 of the Peltier element 10 and is heated there. For good heat conduction from the Peltier element 10 to the air heat conducting fins 14 are arranged. The now heated and very dry air now passes via the line 7 from the other part 12 of the Peltier element 10 to the inlet 8 of the washing container 2 and thus back into the washing 2. The introduced into the washing container 2, heated air is now much dry and has a high absorption capacity for moisture. It rises in the washing container 2 upwards and absorbs the residual moisture on the items to be washed. It will now, as already described above, fed back to the Peltier element 10.

Durch den Einsatz eines Peltierelements 10 ist nur noch eine gegenüber dem Stand der Technik wesentlich geringere Erwärmung des zu behandelnden Gutes notwendig, bei den beschriebenen Ausführungsbeispielen im Teilprogrammschritt "Klarspülen" nur noch etwa um 50 °C, ev. sogar noch niedriger. Dies bedeutet eine wesentliche Energieeinsparung. Durch die Erwärmung der Luft wird deren Feuchtigkeitsaufnahmekapazität bei jedem Durchleiten durch das Leitungssystem 4 wieder erhöht, was zur Verbesserung des Trocknungsergebnisses und/oder zur Verkürzung der Trocknungszeit führt.Through the use of a Peltier element 10 is only one compared to the prior art much lower heating of the material to be treated necessary in the described embodiments in the program step "rinse" only about 50 ° C, ev. Even lower. This means a significant energy saving. Due to the heating of the air whose moisture absorption capacity is increased again with each passing through the conduit system 4, which leads to the improvement of the drying result and / or to shorten the drying time.

Mit der vorliegenden Erfindung ist eine Geschirrspülmaschine 1 bereitgestellt, mit der es möglich ist, unter wirtschaftlichen Gesichtspunkten das im Spülbehälter 2 befindliche Spülgut effizient zu reinigen und zu trocknen sowie den damit verbundenen Energieaufwand so gering wie möglich zu halten.With the present invention, a dishwasher 1 is provided, with which it is possible to efficiently clean and dry the items located in the washing container 2 and to keep the associated energy consumption as low as possible.
